DETAILED DESCRIPTION

[0018] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0019] Embodiment: A three-wheeled vehicle compartment painting device, such as Figure 1-5 As shown, it includes a feeder 1, a spray pipe 2, a spray gun 3, a valve body 4, a ball valve 5, a valve stem 6, a straight nozzle 7, an oblique nozzle 8, a bracket 9, a hollow central shaft 10, a hollow roller 11, a coil spring 12, a ratchet 13, a pawl 14, a spring 15 and a paint spraying mechanism. The top of the feeder 1 is installed with a bracket 9 by bolts. The bracket 9 is fixedly connected to the hollow central shaft 10. The hollow central shaft 10 is connected to the feeder 1 through a pipeline. The bracket 9 is rotatably connected to the hollow roller 11. The hollow central shaft 10 is located inside the hollow roller 11. The hollow central shaft 10 is connected to the hollow roller 11. The spray pipe 2 is wound around the hollow roller 11. The spray pipe 2 is connected to the hollow roller 11. There is a gap between the hollow roller 11 and the bracket 9. It is connected with a coil spring 12, and a pawl 14 is provided on the right side of the inner side of the bracket 9 for rotation. A ratchet 13 is connected to the right side of the hollow roller 11, and the ratchet 13 cooperates with the pawl 14. A spring 15 is connected between the pawl 14 and the bracket 9, and the elastic force of the spring 15 makes the pawl 14 and the ratchet 13 in a coordinated state. A spray gun 3 is connected to the end of the spray pipe 2, and a valve body 4 is provided inside the spray gun 3. A ball valve 5 is provided in the valve body 4, and a valve stem 6 is provided on the ball valve 5. An oblique nozzle 8 is installed on the upper part of the spray gun 3. The oblique nozzle 8 can change the direction of paint spraying, which is convenient for people to paint the bottom of the car or dead corners. A straight nozzle 7 is installed at the lower part of the spray gun 3. The connection state of the spray pipe 2 with the oblique nozzle 8 and the straight nozzle 7 is changed by rotating the ball valve 5.

[0020] like Figure 1 As shown, a hanging rod 16 is also included. A hanging rod 16 is provided on the left side of the top of the feeder 1. The hanging rod 16 can be used to conveniently place the spray gun 3 for people to spray paint.

[0021] like Figure 1 As shown, the feeder 1 also includes a moving wheel 17. The moving wheel 17 is installed at the bottom of the feeder 1. The moving wheel 17 can help people move the entire paint spraying device and reduce the carrying effort.

[0022] like Figure 1 As shown, an armrest 18 is also included. The rear portion of the feeder 1 is provided with the armrest 18. The armrest 18 can help people push the paint spraying device, making it easier for people to move the paint spraying device.

[0023] like Figure 1 As shown, it also includes a support frame 19. The support frames 19 are rotatably provided on both sides of the feeder 1. After the support frames 19 rotate and contact the ground, the friction between the device and the ground is increased to prevent the feeder 1 from moving when spraying paint.

[0024] When the tricycle compartment needs to be painted, first push the handrail 18, and under the action of the moving wheel 17, move the entire paint spraying device to a position suitable for painting, rotate the support frame 19 downward to contact the ground, increase the stability of the feeder 1, and then move the spray gun 3, thereby driving the spray pipe 2 to rotate counterclockwise and pull it out from the hollow roller 11, the coil spring 12 is deformed, and the hollow roller 11 rotates counterclockwise to drive the ratchet 13 to rotate counterclockwise, and the pawl 14 swings adaptively under the action of the spring 15, and the pawl 14 does not hinder the ratchet 13 from rotating counterclockwise. When the spray pipe 2 is pulled out to a suitable length, stop pulling the spray gun 3, and the pawl 14 jams the ratchet 13, so that the hollow roller cannot rotate clockwise under the action of the coil spring 12. Then, according to different painting positions, rotate the valve stem 6 to drive the ball valve 5 to rotate, and adjust the spray pipe 2 and the straight The nozzle 7 or the oblique nozzle 8 is connected. If painting is to be done on the flat surface of the carriage, the spray pipe 2 is connected to the straight nozzle 7. If painting is to be done on the bottom of the carriage or in a dead corner, the spray pipe 2 is connected to the oblique nozzle. In this way, the spray state of the nozzle can be adjusted according to the actual spraying situation, thereby improving the practicality of the device. When the painting is completed, the pawl 14 is rotated until it does not get stuck on the ratchet 13. Under the action of the coil spring 12, the hollow roller 11 rotates clockwise, thereby driving the spray pipe 2 to wind clockwise on the hollow roller 11. After winding to the appropriate position, the pawl 14 is lowered, and the pawl 14 gets stuck on the ratchet 13. The spray pipe 2 stops winding, and then the spray gun 3 is placed on the hanging rod 16. In this way, the painting is completed. Because the spray pipe 2 is automatically wound on the hollow roller 11 under the action of the coil spring 12, it is convenient for people to put away the spray gun 3, thereby achieving a convenient effect.
